Red Bull RB15

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.

What are the red dots on the brake intake for? To not forget to remove them If the air&track temperatures Climb?

Hi res of trimmed, low downforce front wing

How exactly is it trimmed?! Its the same one with 5 elements just with adjusted angle of attack to align with the low DF rear wing.
Flap tips are trimmed

Optical illusion. Different attack angle. The same wing as in Spa.

My guess is "photogrammetry", where they use video / still photography of those round targets to determine geometry of local components. Since they 'know' that the decals / targets are round, they can figure out (with software) pretty precisely what's happening. Like fractions of millimeter.

Or maybe they just like red circles. F1, so who really knows...

The Formula1.com official FP2 broadcast has excellent footage of the RB15 suspension in action.

At ~ 11:20 (at least with the English language version) there's an in-car view of Albon going a bit wide at turn 1 and running over a couple "sleeping policemen" (low FIA-type speed bumps). Then there's a trackside view of the same thing.

The front suspension remains rock hard with the tire absorbing most of the vertical input. Then the rear suspension shows large vertical compliance over the bumps.

At the end there's a beautiful side view of the car going over the last sleeping policeman, and it shows the tea-tray deflecting smoothly and lightly over the bump. There are some sparks from the titanium rub strips underneath, but don't be fooled by that-- the tea-tray looks more softly sprung than the front or rear wheels!

Guessing this is all pretty typical of current F1 car setup.

To my eyes, the chord length (i.e., the width, top-to-bottom) of the uppermost flaps is narrower. Which is exactly what Ferrari did to their FW at Spa (and Monza) and what Mercedes has done with their FW at Monza.

I think you are absolutely right. You can see that best right next to that little splitter structure, on the hungary Pic it ends right at its top level, on the italy Pic it is noticable lower.

Photogrammetry needs multiple camera angles with a significant overlap (more than 60%) in order to create a decent triangulation.

Good reference point! There are a couple more, too.

Last year wing was way more extreme.

Shows they're much less limited by kW this year.
I guess so, yet stuck behind Perez for most of the race. The car, or rather the power unit, was disappointing in Monza.

In clean air he was faster than Leclerc, then again so was Hamilton, but this is not the thread for this discussion.

Overtaking Perez was easy last week at spa with much bigger straights line and power demand. Max said the pu hitting rev limiter

Key for overtaking at Monza is good exit speed at Parabolica. I think that Redbull and Mercedes aero config is not giving enogh stability in Parabolica because of less DF at rear because of skinny RW for good max speed at straights. Ham and Bot were also struggling with Lec.

Any chassis or aero updates coming for Singapore. I guess they will be starting to shift focus towards RB16 more and more around this time

Wdc went to Ham with WCC to merc. No need to work much for this season.
